PERTH has had one of its coldest winter nights, with air temperatures dropping to near freezing.
We need to prevent supercooling of our pond water to keep fish from stressing. To do this, we need to decrease the water flow rate to cut evaporative cooling, decrease aeration to reduce cooling by air, add salt to your pond at a rate of 1-5g/L, add vitamin C to their water, and reduce feeding to a minimum (and only during the warmer parts of the day – see also,

If you’re unsure about any of these, call us in to scope out your set-up.
